Embodiment 1

[0039] The embodiment of the present invention provides a kind of processing method of compound fu brick tea, specifically comprises the following steps:

[0040] The raw materials are blended according to the ratio of Taoyuan large-leaf group species: Anhua Yuntai large-leaf group species: dried jasmine flower: dried tea tree flower = 40:50:5:5. After steaming, add 4wt% of the fermentation broth of mixed bacteria and stir evenly , secondary stacking fermentation for 48h, wherein: the fermented liquid of the mixed bacteria is composed of (1-10) ×10 4 cfu / ml Aspergillus niger and (1-10)×10 4 cfu / ml Lactobacillus composition;

[0041] Add fermented liquid 10wt% containing Aspergillus coronis strain GTQM2021-01 (the dominant strain isolated from Fuzhuan brick tea, the effective number of viable bacteria is (1-10) × 10 4 cfu / ml), and stir evenly, leave standstill for 20-60min, allow the fermented liquid of Aspergillus coronis strain GTQM2021-01 to be fully absorbed by the black ...

Embodiment 2

[0044] The embodiment of the present invention provides a kind of processing method of compound fu brick tea, specifically comprises the following steps:

[0045] The raw materials are blended according to the ratio of Taoyuan large-leaf group species: Anhua Yuntai large-leaf group species: dried jasmine flower: dried tea tree flower = 45:55:6:4. After steaming, add 5wt% of the fermentation liquid of mixed bacteria and stir evenly , secondary stacking fermentation 72h, wherein: the fermented liquid of mixed bacteria is made up of (1-10) ×10 4 cfu / ml Aspergillus niger and (1-10)×10 4 cfu / ml Lactobacillus composition;

[0046]Add fermented liquid 12wt% of Aspergillus coronis strain GTQM2021-01 (from the dominant strain isolated from Fuzhuan brick tea, the number of effective viable bacteria is (1-10) × 10 4 cfu / ml), and stir evenly, leave standstill for 20-60min, allow the fermented liquid of Aspergillus coronis strain GTQM2021-01 to be fully absorbed by the black hair tea, wa...

Embodiment 3

[0049] The embodiment of the present invention provides a kind of processing method of compound fu brick tea, specifically comprises the following steps:

[0050] The raw materials are blended according to the ratio of Taoyuan large-leaf group species: Anhua Yuntai large-leaf group species: dried jasmine flower: dried tea tree flower = 42:48:6:4. After steaming, add 5wt% of the fermentation broth of mixed bacteria and stir evenly , secondary stacking fermentation 72h, wherein: the fermented liquid of mixed bacteria is made up of (1-10) ×10 4 cfu / ml Aspergillus niger and (1-10)×10 4 cfu / ml Lactobacillus composition;

Abstract

The invention discloses composite Fuzhuan tea based on mixed fermentation of probiotics and eurotium cristatum and a processing method of the composite Fuzhuan tea. The processing method comprises the following steps: steaming a tea base obtained by blending dried jasmine flowers, dried tea flowers and large-leaf group species, adding fermentation liquor containing lactobacillus and aspergillus niger, uniformly mixing, and carrying out secondary pile fermentation; then adding aspergillus cristatus strain fermentation liquor, uniformly mixing, and standing for material waking; steaming the fermented raw dark green tea, and pressing the steamed raw dark green tea into Fuzhuan tea; after the Fuzhuan tea is placed in an automatic drying room for eurotium cristatum growing, the temperature of the drying room is increased, the Fuzhuan tea with eurotium cristatum growing is taken out and dried, and the Fuzhuan tea is obtained. Probiotics and dominant eurotium cristatum are added in the fermentation process, so that microbial metabolites such as polysaccharide compounds and simple phenolic acid are generated, and the microbial metabolites have the function of coordinating intestines and stomach; the processed Fuzhuan tea is rich and lasting in jasmine flower fragrance and tea flower fragrance, the tea soup is mellow, sweet and refreshing in taste, the drinking value of the tea leaves can be reserved, and the fermentation flavor and the health-care effect of fermented products are achieved.

Description

technical field [0001] The invention belongs to the technical field of tea preparation, and more specifically relates to a compound Fuzhuan brick tea based on the mixed fermentation of probiotics and golden flower fungi and a processing method thereof. Background technique [0002] Fuzhuan tea is a special post-fermented tea. The process of Fuzhuan brick tea processing includes: raw material processing → steam stacking → pressing and shaping → blooming and drying → finished product packaging. The specially fermented Fu brick tea not only has the effects of promoting body fluids to quench thirst, digestion and greasy, but also has various health effects such as vitamin supplementation, lipid-lowering weight loss, anti-oxidation, anti-tumor, anti-radiation and scavenging free radicals. [0003] Jasmine is a famous scented tea raw material and an important essence raw material, which has various nutrients and health care ingredients. Tea tree flowers are rich in functional co...
